MARSEC 2 is defined as which of the following?

• A. Baseline
• B. The CG's most focused security posture
• C. Increased security posture, perception of heightened general risk
• D. No change in security posture

Answer: (C)

MARSEC levels adjust security posture in response to risk. When risk is elevated, the posture increases to require more security measures beyond the baseline, reflecting a heightened general risk. This means heightened vigilance, more thorough screening or checks where appropriate, and additional security actions, without yet reaching the maximum measures used for imminent threats. The baseline description fits Level 1, no change describes no adjustment, and the most focused posture describes the maximum security measures used for imminent or highly elevated risk. Therefore, MARSEC 2 is best described as an increased security posture in response to heightened general risk.
